Q: Why is the test result abnormal or below normal?
A: ① Please check whether the air inlet or outlet is covered or liquid has entered.
②
Gently shake the detector during detection to increase the interaction with surrounding air.
③ The sensor may be not recovered, Please place the detector outdoors for ventilation.
Q: Why data reading is unstable?
A: If the airflow in the current sampling space is in an unstable state, such as strong wind,
the concentration of particulate matter in the air will be unevenly distributed, and will vary
greatly with the surrounding airflow, resulting in large dierences in measured values.
Q: Why humidifiers can cause rising particulate matter readings?
A: Our sensors use the principle of light scattering. When using a humidifier, the humidifier
will spray many small droplets of water. Excessive humidity and moisture in the air will cause
dust particles to absorb water and swell, which will aect the scattering of light and cause
deviations in sensor readings.
Q: Why is the data reading very high/over-range after the detector is turned ON?
A: As being packed in ink printed package box over time may interfere with the sensor due to
the remaining organic volatile residue inside the package. Therefore, after unpacking, please
put the detector in a ventilated place to help accelerate its data recovery.
Q: Why is the data high after booting?
A: The reason why the data is high when you first turn on the sensor is that when the sensor
starts to work, the fan will run at full speed, and it will take a while (about 1-2 minutes) for
the fan to run stably. At this time, the airflow in the air duct will be stable, and the data will
gradually become stable.
Q: AQI/ PM2.5 and other values, why the measured value is inconsistent with the
ocial announcement?
A: The AQI/PM2.5 shown on the display is a measurement of the space where the device is
located. The measured value published on the Internet or ocial websites is the average
value of several monitoring points, and each measurement point will be dierent. At the
same time, according to the regulations of EPA and WHO, the AQI value is calculated based
on the highest value among the five pollutants in the atmosphere on that day. In the past
ten years, the local AQI in the United States has basically been calculated with the value of
PM2.5/10, and sometimes with the value of O
3.
